Problems solved by technology

[0005] 2. Dropping bottles are easy to break, pipetting is easy to leak, and most of the fixing agent components are corrosive strong acids and strong alkalis, which are dangerous, and the errors in quantitative sampling items are relatively large, which is not conducive to the uniformity of sampling and testing

Abstract

The invention discloses a portable water sample fixative feeding device which comprises a box and an upper cover which matches the box. The box and the upper cover both contain a protective lining and an aluminum alloy outer shell layer. The protective lining fit and is fixed on the inner side of the aluminum alloy outer shell layer. The inside of the box is a cavity structure. Multiple fixative wrappers are fixedly arranged inside the cavity structure through the protective lining. Each fixative wrapper contains a reagent bottle and a fixative filling injector which is arranged at the bottleneck of the reagent bottle. The fixative filling injector is equipped with a fluid-discharge tube which is communicated with the reagent bottle. A free end of the fluid-discharge tube is provided with a protective cap for sealing. By the use of the portable water sample fixative feeding device, the link of preparatory work for water sample fixative feeding is reduced, and efficiency is enhanced; it is guaranteed that sample data is more uniform and stable; during transportation, the filling injector is equivalent to a bottle cap such that a fixative will not be splashed out of the bottle; use safety is raised; and the device provided by the invention has a quantitative continuous feeding function.

Description

technical field [0001] The invention relates to a portable water sample fixative adding device, which belongs to the technical field of water quality monitoring. Background technique [0002] At present, when sampling in the existing water quality monitoring field, a fixative is added for protection according to the needs of the project during sampling, so as to ensure the accuracy of the experimental data. For example, in the microbial detection of chlorine-treated water samples (such as tap water, swimming pool water, and medical wastewater), 2 mL of 115% sodium thiosulfate aqueous solution should be added to every 500 mL of water sample to remove residual chlorine and avoid residual chlorine. The bactericidal effect on water samples will affect the results. In the detection of heavy metal wastewater, 10ml of strong acid must be added to every 1L of water sample to fix the water quality before sampling to ensure the stability of water quality before detection.
